Admin page problems

[MaxRPM]

After updating to the newest version i am not able to update any information from my admin page, such as setting customer discounts. When i select their discount from the drop down box and click update it brings up a blank customer page and does not update the other. I have also tried to search for files through the developers tool kit and am getting an error that there was no text entered for the search. It seems as though all of the text fields in the admin page are not responding. The website still works fine and i am able to edit the php directly.

ZenCart 1.3.8a
database patch level 1.3.8
php version 5.2.11

Thanks

Ma,
Click on the orange tab on the top of this page called Tutorials/FAQ

1. search for: blank page
2. download the debugger

Hi, thanks for the tip however i've ran the debugger and it did not create a log file. There is no error (would it be stated at the top of the screen) when i try to update the information it only changes the screen to a blank customer page.
